first of all quick cache seems to be a great plugin. Easy setup and important settings balance each other. Nevertheless I have two questions:
1. Is there any support for mobile plugins planned? E.g. If I use a different theme for mobile devices I would need a different cache file for those.
2. As updating cache files in the correct moment seems to be the hardest challenge for caching engines, I would love to see a settings named "update the chache file each time a logged in user loads the page". In this way I can make changes anywhere in wordpress, and then just load the affected pages while I am logged in, which will automatically updated the correct cached files.
This way editors could make their changes, look if everything looks fine, and without knowing they automatically updated the cache files.
Keep it up,
